24V 3A Power Supply 72W AC/DC Adapter

Product Details

Product Overview

The 24V 3A Power Supply 72W AC/DC Adapter delivers regulated 24V DC at up to 3A, designed for applications that require continuous, reliable power in a compact form factor. The universal AC input (100–240Vac, 47–63Hz) ensures compatibility with power grids worldwide, while the standard 5.5×2.1mm DC barrel connector mates directly with most 24V equipment. Measuring just 90×46×32, the 24V 3A Model fits neatly into tight enclosures and equipment racks without obstructing adjacent outlets.

Design & Build Quality

The 24V 3A Model employs a high-frequency switching topology with premium 105°C-rated capacitors, achieving 88% energy efficiency (DoE Level VI) and keeping surface temperature below 50°C under continuous full load. This thermal headroom makes the model suitable for enclosed cabinets, equipment racks, and installations where airflow is limited. The fanless design ensures completely silent operation — no mechanical noise in studios, offices, or bedrooms.

Typical Applications

With 72W of continuous output capacity, the 24V 3A Model serves a broad range of 24V DC loads:

• LED Strip Lighting — Drives SMD 5050, 2835, and 5630 strips up to approximately 6 meters, with stable current delivery that prevents flicker and color shift at the far end of the run.

• Surveillance Systems — Powers IP cameras, dome cameras, and NVR accessories; low ripple output (≤120mV) prevents image artifacts on analog and hybrid systems.

• Networking Equipment — Compatible with routers, switches, modems, and VoIP adapters requiring 24V DC input.

• 3D Printers & CNC — Provides stable power for control boards, hot-end heaters on entry-level machines, and stepper motor drivers.

• Industrial Controls — Suitable for PLC I/O modules, sensor arrays, and access control panels operating within the specified temperature range.

Four independent protection circuits in the 24V 3A Model operate autonomously to safeguard both the unit and connected equipment:

• Over-Voltage Protection (OVP) — Shuts down output if voltage exceeds safe threshold; auto-recovers when fault clears.

• Over-Current Protection (OCP) — Limits output current to prevent damage from overloaded downstream wiring.

• Short-Circuit Protection (SCP) — Instantly cuts output when a short circuit is detected.

• Over-Temperature Protection (OTP) — Thermal shutdown activates if internal temperature exceeds design limits; resumes once cooled.

All protection modes are non-latching — the model automatically restarts after the fault condition is removed. Full UL/CUL, FCC, CE, and CB certifications support compliance for commercial, industrial, and residential installations worldwide.

Every 24V 3A Model carries a 3-year warranty covering manufacturing defects. Technical support assists with compatibility verification, cable length selection, and connector configuration. OEM and ODM services are available for custom branding, cable lengths, and plug styles on bulk orders (MOQ 1000 pcs, 7–10 day lead time).

TQ Power manufactures AC/DC adapters ranging from 5W to 500W, with every unit undergoing 100% burn-in testing, hi-pot verification, and output regulation validation before shipping. ISO 9001 certified quality management and UL/CE/FCC/CB listings support worldwide distribution.
